Question

有没有办法在Python中获取更具体的错误消息？ E.g完整错误代码或至少发生错误的行，无法找到的确切文件而不是通用"The system cannot find the file specified")

for file in ['C:/AA/HA.csv', 'C:/AA1/HA1.csv']:
        try:
            os.remove(file)
        except OSError as e:
            pass
            print(getattr(e, 'message', repr(e)))
            #print(getattr(e, 'message', repr(e)))
            #print(e.message)
            #print('File Not Removed')

以下打印两次：

FileNotFoundError(2, 'The system cannot find the file specified')

虽然这很棒，但是有没有办法获得更准确的错误消息以进行错误修复？

以下内容会停止作业，但会在控制台中显示exact line being 855以及文件directory ''C:/AC/HA.csv''.

os.remove('C:/AA/HA.csv')
Traceback (most recent call last):
  File "C:/ACA.py", line 855, in <module>
    os.remove('C:/AC/HA.csv')
FileNotFoundError: [WinError 2] The system cannot find the file specified: ''C:/AC/HA.csv''

请参阅traceback模块：

Traceback (most recent call last):
  File "C:\test.py", line 6, in <module>
    os.remove(file)
FileNotFoundError: [WinError 3] The system cannot find the path specified: 'C:/AA/HA.csv'
Traceback (most recent call last):
  File "C:\test.py", line 6, in <module>
    os.remove(file)
FileNotFoundError: [WinError 3] The system cannot find the path specified: 'C:/AA1/HA1.csv'

输出：

        // Create an instant object from the timestamp
        Instant instant = Instant.ofEpochMilli(3600);
        instant.atZone(ZoneOffset.UTC);

        //Add X number of days to instant
        instant.plus(1, ChronoUnit.DAYS);


        // Create a date formatter
        SimpleDateFormat formatter = new SimpleDateFormat("YYYY-MM-DD HH:MM:SS");
        formatter.setTimeZone(TimeZone.getTimeZone("UTC"));

        // Create the date from instant & format it from date formatter
        Date date = Date.from(instant);
        String formattedDate = formatter.format(date);
        System.out.println(formattedDate);
